(3)保持温度不变,向溶液中通入氯化氢气体使c(H+)=0.004mol/L,此时c(CH3COO-)=?
已知25℃时,0.1mol/L的醋酸溶液中,c(H+)=0.001mol/L(CHCOOHCHCOO+H+)(电离度a=已离解的分子数/起始分子总数x100%)
(1)计算该温度下,醋酸的电离度和电离平衡常数(醋酸平衡时浓度近似为初始浓度)
(2)保持温度不变,若c(CHCOOH)=0.2mol/L,溶液中c(H+)=?
已知25℃时,0.1mol/L的醋酸溶液中,c(H+)=0.001mol/L(CHCOOHCHCOO+H+)(电离度a=已离解的分子数/起始分子总数x100%)
(3)保持温度不变,向溶液中通入氯化氢气体使c(H+)=0.004mol/L,此时c(CH3COO-)=?
有过程吗
